HMI’s patented expandable frame for the aluminum and security storm door helps make installation a snap and the appearance beautiful. It allows for adjustments up to 3/8”. Made of extruded aluminum it creates a perfectly level opening to fit the storm door.
All doors manufactured by HMI are coated with a “state-of-the-art” powdercoat finish to give years of trouble free enjoyment. The metal is cleaned and treated with chemically balanced detergents. The doors are then top coated with a powdercoating that is electrostatically applied and finally baked at 400° offering excellent adhesion, hardness and weather resistance.
